Automatic Solar Street Light

A solar cell is a device that converts light energy (mainly sunlight) into electrical energy. The principle is the photovoltaic effect, that is, based on the built-in electric field of the PN junction, the photogenerated carriers are separated and reach both sides of the junction to generate a photovoltage, which is connected to an external circuit to obtain power output. The power of solar cells is related to the intensity of light. The stronger the light, the stronger the power output.

Solar energy systems are easy to install, easy to expand, and easy to disassemble. At the same time, using solar energy is also very economical and there is no energy consumption during the operation. In addition, the system is resistant to mechanical wear and tear; a solar system requires reliable solar cells to receive and store solar energy. Generally, solar cells have the following advantages:
1) High charge absorption capacity;
2) Long cycle life;
3) Good rechargeability;
4) No maintenance required.

1) High energy density;
2) High working voltage;
3) No memory effect;
4) Long cycle life;
5) No pollution;
6) Light weight;
7) Small self-discharge.

Overcharging refers to the behavior of continuing to charge the battery after it is fully charged through a certain charging process. For Ni-MH batteries, overcharging produces the following reaction:
Positive electrode: 4OH- - 4e → 2H2O + O2↑;①
Negative electrode: 2H2 + O2 → 2H2O②
Since the negative electrode capacity is higher than the positive electrode capacity during design, the oxygen generated by the positive electrode passes through the separator paper and combines with the hydrogen generated by the negative electrode. Therefore, under normal circumstances, the internal pressure of the battery will not increase significantly. However, if the charging current is too large, Or if the charging time is too long, the generated oxygen will not be consumed in time, which may cause the internal pressure to rise, battery deformation, leakage and other adverse phenomena. At the same time, its electrical properties will also be significantly reduced.
